A heavy downpour has shut down Istanbul, flooded homes and roads and killed at least two people. Rescuers worked overnight to save hundreds of people stranded at their workplaces, while bystanders helped countless others. The downpour Wednesday night flooded homes and businesses and inundated roads and underpasses, stranding vehicles and causing traffic chaos. Local media reported two deaths. One person was electrocuted after stepping in a puddle at a park and another slipped on a sidewalk and hit their head. Rain was continuing to fall Thursday.
